In early November, it was revealed the High Court had thrown out the appeal, leaving Siemens Mobility and TfL free to go ahead and sign the contract.

That contract has now been reached, in a £1.5bn deal which will create up to 700 jobs in East Yorkshire.

William Wilson, managing director rolling stock at Siemens Mobility Limited, said: “These state-of-the-art trains, which are track-friendly and future-proofed for a long life, will transform the travel experience for the 700,000 daily Piccadilly line passengers.

“We’ve thought about travellers at every stage of the process and as a result the trains feature walk-through carriages with wider doors, improved access to make them easier to get on and off, and feature full air-conditioning – a real challenge in hot tunnels.”

From 2023, new spacious ‘Inspiro London’ trains will be delivered for testing on the Piccadilly line, with current estimates indicating the first of these trains will be serving customers in 2024.

The state-of-the-art tube trains will significantly improve the experience of millions of customers, with wider doors and longer, walk-through, fully air-conditioned carriages.

In addition, in-train information systems will help all customers plan their onward journey more easily.

The initial order placed by TfL will see 94 trains manufactured in Goole.

Work on the factory is now expected to get underway, at a cost of around £200m.
